Bench Test FIRST

摘要

SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA) was originally deployed at Grant County Public Utility District (GCPUD; Ephrata, Washington, U.S.) in the late 1980s to improve response times to outages. Most communication throughout GCPUD's 2800-sq-mile (7250-sq-km) rural service territory was provided by a 2400-baud radio system with a SCADA protocol that was proprietary and unique to GCPUD. As we entered this century, the hallmarks of this system included bandwidth limitations, lack of expandability and communications failures. So in 2002, GCPUD initiated a project to upgrade its entire system.
